MESSAGE
An E-Stop has been pressed or the back service doors are open.
Solutions:
Clear all "E-STOP" buttons and press the "E-STOP RESET" button.
Close back doors.
Check E-Stop circuit safety relay.
Cycle has been aborted, because the front door proximity sensor did not detect any-
thing after 3 seconds of zero motion.
Solutions:
Check if the sensor is aligned with the target when the door is closed. If not, you
may need to make adjustments.
Verify you have enough air pressure to close the door. Sometimes you have enough
to close the door but not enough to compress the rubber seal. In this situation
the sensor's target will be slightly out of its detection range.
The hydraulic unit is drawing more current than normal, and has tripped the overload
relay.
Solutions:
Check if you have enough oil.
Check the power. Reference schematics.
Call technical support.
Tool ID is active but no valid tool ID.
Solutions:
Check if the tooling supports tool ID. If yes, confirm the cable is connected. If no,
then turn off tool ID.
Test the cable by performing a point to point continuity test.
Reference the schematics.
